BUILDING MATERIAL MIXTURE Russian patent published in 2006 - IPC C04B24/24 C04B28/00 C04B11/00 

FIELD: industry of building materials.

SUBSTANCE: invention relates to a building material mixture. The building material mixture comprises material chosen from the group consisting of gypsum, calcium hydroxide, cement and their mixtures, and also - polysaccharide or derivative of polysaccharide with particles size less 15 mcm taken in the amount 2 weight % maximally, particles size less 10 mcm taken in the amount 2 weight % maximally, and particles size less 5 mcm taken in the amount 1 weight % maximally, and if necessary the mixture comprises quartz sand or lime sand, water repellant, synthetic dispersion powder, cellulose fibers and/or synthetic fibers, pore-forming additive and light filling agents in the following ratio of components, weight %: material from the group containing gypsum, calcium hydroxide, cement or their mixtures, 1-99.99; polysaccharide or derivative of polysaccharide, 0.001-5; quartz sand or lime sand, up to 90; synthetic dispersion powder, up to 10; light filling agents, up to 10; water repellant, up to 1; pore-forming additive, up to 0.1; cellulose fibers and/or synthetic fibers, up to 15 wherein the content of components that the mixture comprises when needed doesn't mean 0 simultaneously, and polysaccharide or derivative of polysaccharide is prepared by the known technology. Invention provides improvement of physical-chemical properties of building mixture.

EFFECT: improved properties of building material mixture.
